초록

A construction is provided to aerodynamically affect a jet engine nacelle in its intake lip area primarily by forming and pivotally arranging flaps on a radially outer circumferential sector of the intake lip such that from a first extreme position, in which they are adapted to a cruise lip geometry, they can be moved into a second extreme position, in which they radially expand the outer contour of the intake lip while providing and exposing air blowoff ducts with their rear side, said ducts terminating at the outer wall of the nacelle at essentially a ...

청구항

Jet engine nacelle construction comprising a jet engine nacelle having annular entry lip means surrounding a nacelle centerline and serving to guide air into a jet engine, a plurality of pairs of first and second blowoff flaps movably mounted to the entry lip means for movement between a closed position with the first blowoff flap aligned with adjacent radially outer wall portions of the entry lip means and the second blowoff flap aligned with the adjacent radially inner wall portion of the entry lip means and an air blowoff position with the first and s...
